MAX MERZ, OF NEW YORK, N. Y.

SPECIFICATION forming part of Letters Patent No. 266,042, dated October 1'7, 1882.

Application filed July 1, 1882.

T 0 all whom it may concern:

Be it known that I, MAX MERZ, of the city, county, and State of New York, have invented certain new and usefulImprovements in Gages for Joining Wood, of which the following is a specification.

This invention has reference to an improved device for marking off the guide-lines for cutting mortises and tenons of dovetail and other shape in joining wood-work for drawers and other articles of wood; and the invention consists of two longitudinally-recessed and transversely-connected main pieces or strips, which support a number of adjustable marking-pieces that are set at a proper distance from each other, as required for marking off the cuttinglines. A fixed end plate serves as a stop for laying on the gage to the wood, while longitudinal side strips that are adjustable along the supporting main strips admit themarking off of the cutting-lines at some distance back of the edge of the wood.

In the accompanying drawings, Figure 1 represents a side elevation, with a part broken out, of my improved gage for laying off the cutting-lines for the mortises and tenons in joining wood-work. Fig. 2 is a side view of the same, shown with the longitudinal side strips adjusted on the body of the gage; and Figs. 3 and 4 are respectively a vertical transverse section on line 00 as, Fig. 2, and an end view of the gage.

Similar letters of reference indicate corresponding parts.

A A in the drawings represent the supporting main strips of my improved gage for laying off the cutting-lines in joiningthe edges of wood-work. The main strips A A are made of equal size and of suitable metal and connected by transverse fastening-screws a. They are longitudinally recessed at the upper part, the recesses facing each other and being of dovetail or other shape for supporting a number of marking-pieces, B, which extend at right angles from the main strips AA, and are beveledat one side and straight at the other side. The shanks of the markingeiieces B B are recessed, so as to fit closely into the longitudinal recesses of the main strips, the upper projecting parts of the marking-pieces being equal in (N0 model.)

} thickness to the thickness of both main strips together.

The marking-pieces B are capable of being adjusted to any distance from each other in the main strips A A, after which the screws are tightened, so as to prevent them from shifting or changing their position in the main strips. Bysetting the markers B into proper position in the main strips and placing then the gage in position along the edge of the board the lnortises and tenons are quickly marked off by running a sharp nail or other marking implement along the edges of the markers B. By then cutting the inortises and tenons in the edges of the boards they may he jointed with perfect accuracy.

To one end of the main strips A A is attached a fixed stop-plate, U, which is set against the end of the board when the gage is to be used for marking off the cutting-lines. The main strips A A are further provided with longitudinal side strips, D D, which are connected at the ends by means of transverse screw-bolts (I, said side strips being secured tightly, either flush with the edge of the main strips A, so as to he placed against the edge of the wood to be jointed, or at some distance from the same along the body of the main strips A A, as shown in Fig. 2, the latter position being used when the cutting lines are desired to be marked off at some distance from the edge of which are not to be visible at the front part of the wood, are required.

My improved gage may be made up in any suitable size and material, and forms a cheap and very convenient means for carpenters,

laying off their guide-lines for cutting the mortises and tenons in joining wood.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- 1. A gage for laying off the cutting-linesin joining wood, which consislsof longitudinallyrecessed supporting main strips A A, of a series of adjustable marking-pieces, B B, having shanks fitted into the recesses of the main strips, and of longitudinal side strips, D D, substantially as set forth.

2. The combination of longitudinally-rethe wood, in case so-called covered joints,

cabinet-makers, and other workers in wood for v IOO cessed main strips A A, adjustable marking- In testimony that I claim the foregoing as pieces B 13, having shanks fitting into the remy invention I have signed my name in presoesses of the main strips, longitudinal side ence of two subscribing witnesses.
